Improved railway-switch

Letters Patent No. 88,898, dated April 13, 1869.

IMPROVED RAILWAY-SWITCH.

The Schedule referred to in these Letters' Patent and maklng part o( the lame.

To all whom it may concern Beit known that LF. P. PERDUE, of Atlanta, in the count-y of.Fulton, and in the State of Georgia, have invented certain new and useful Improvements in Railroad-Switches; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theV accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construe tion and general arrangement ofv a railroad-switch, which will be hereinafter more fully described.

AIn order to enable others skilled in the art towliich my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Fignre 1 is a plan view, and

l Figure 2- an end view.

A A' represent the rails of the main track, and B B', those of the side track,

The side-track rails are all stationary, but part of the main track, marked C C', is movable, so as to be changed om the main to the side track when so desired.

This'is accomplished by' rods D D, connecting the two rails O and C', and a crank-lever, E, which by means of hinged rod F, is connected with the rail G, another rod'G,.then connects the hinged rod F. with one of the rods D, so that by turning the crank-lever E, therails 0 and O are moved at the same time to connect either with the main or the side track.

To the rail'C is secured a rod, H, which operates the signal I,I showing to the engineer of the approach 'ing train, whether the switch is open or not.

By this. means there` is no danger of having wrong signals, as the position of the signal-board is always depending upon the position of the switch'.

At the point where the inner rails A and B' of the two tracks should cross each other, is one movable rail J, which is turned from one to the other, forming connection on 'the main track or the'side track, according to the position of theswitch already described.

This movable rail J is secured at one end to a clamp, E, pivoted to the cross-tie, and at the other end connected by a rod, L, toa bent lever, M, which Vin its turn is connected-by a rod, N, running under the middle rail B to another bent lever O, which is operated by the lever E, the hinged rod F extending for 'that purpose to the said lever'O, between the two railsof the main track.

Itl will be seen-that by this arrangement, I operate the movable rail .I at the. same time as the rails O O' are changed. l

I am aware that devices for simultaneously operating the frog, switch, and signal have been known -before, hence, I do not broadly claim' devices for this pnrpose.

What I claim, is-

The arrangement of thelever E, hinged rod'F, bent levers O and M, and rods G and'N, with the rails G C', and pivoted rail J, in combination with the rod H, and signal I, all substantially as and for the purposes set forth.

v In testimony that I claim the foregoing, I have here-` unto set my hand, this l1st day of August, 1868.
